Description

The Bently Nevada 138708-01 is a Shaft Absolute I/O Module with Internal Terminations designed for machinery protection and condition monitoring within the 3500/42M Proximitor/Seismic Monitor system. Interfacing directly with the 3500/42M main monitor board via the 3500 backplane, the module routes field signals from proximity, Velomitor, or Seismoprobe transducers to condition raw signal inputs and measure critical parameters like shaft absolute vibration. The board continuously feeds static and dynamic variables to the 3500 Rack Configuration Software and host monitoring systems, providing continuous alarm setpoint evaluation against active static values to safeguard industrial rotating machinery.

Features

  • Direct connection for internal field wiring terminations without requiring external termination blocks
  • Input signal processing for proximity transducers, Velomitors, and Seismoprobes
  • Integrated signal routing for shaft absolute vibration measurements within the 3500/42M Proximitor/Seismic Monitor
  • Standard 8-pin and 10-pin Euro style internal connector header compatibility

Applications

  • Shaft absolute vibration measurement on industrial rotating machinery
  • Continuous machinery protection and alarm monitoring
  • Operations and maintenance asset condition monitoring in 3500 Series racks

Installation Guidelines

  • Install the 138708-01 module into the rear slot of the 3500 rack directly behind the corresponding 3500/42M main monitor board.
  • Wire field transducer leads directly to the internal Euro style screw terminal connectors.
  • Verify that external termination blocks are not used with this module, as it uses direct internal terminations.
  • Secure the card in place using the chassis retaining screws to ensure stable ground contact through the 3500 rack frame.
